Description

Technical Field

[0001] This utility model relates to the field of bamboo and wood product processing technology, specifically to an automatic CNC tenon and mortise grooving integrated machine. Background Technology

[0002] In the bamboo and wood product processing industry, tenons, mortises, and straight grooves are the core structures for connecting components. Their processing quality directly determines the product assembly accuracy, while processing efficiency affects production progress. In traditional processing methods, the processing of tenons and mortises and straight grooves needs to be completed step-by-step on multiple machines: first, the tenons are processed by a milling machine, then the grooves are processed by a grooving machine. During this process, manual handling and flipping of the boards are required to adjust the processing direction. This process not only consumes a lot of manpower, but also causes problems such as excessive tenon-mortise clearance and groove position deviation due to human error, which seriously affects product quality. At the same time, the connection between processes on different machines relies on manual intervention, resulting in frequent interruptions in the processing flow and difficulty in improving production efficiency; moreover, manual operation poses the risk of mechanical injury, and it is even more difficult to ensure the consistency of processing of each workpiece during mass production, which restricts the stability of large-scale production.

[0003] In existing technologies, such as the Chinese invention patent "Double-Workbench Milling Machine for Aluminum-Wood Doors and Windows" with patent number 201810144431.3 (application publication number CN108214745A), the simultaneous milling of male and female tenons is achieved through a high and low double-workbench design. This solves to some extent the drawbacks of traditional single-workbench milling machines that require frequent tool changes or the configuration of two machines, thus improving the efficiency and accuracy of male and female tenon processing. However, such equipment only focuses on the male and female tenon processing stage and cannot take into account the processing needs of straight grooves. As a result, after the male and female tenon processing is completed, the board still needs to be transferred to other equipment for groove processing. The problem of insufficient process continuity still exists, making it difficult to meet the production needs of bamboo and wood products for multi-process integration, high efficiency, and low cost.

[0004] Therefore, how to further integrate the processing function of straight grooves on the basis of existing male and female tenon processing equipment to achieve continuous and integrated processes has become a technical problem that urgently needs to be solved in this field.

The lower edge of the second conveyor belt extends along the conveying direction and is provided with a guard edge that is higher than the conveying plane of the second conveyor belt to limit the plate from falling to a lower position. At least one set of second rolling pressure rollers is provided above the second conveyor belt. When the trough processing unit is processing the plate, the second rolling pressure rollers press the plate and assist the second conveyor belt in stabilizing the conveying of the plate.

[0039] Feed hopper 13: Reference Figure 1 and Figure 2 As shown, the material is fixedly installed above the feed end of the first conveying mechanism 2. It is made of steel plate welded into a rectangular box structure, which can accommodate multiple layers of stacked plates T. The bottom of the feed bin 13 is provided with a discharge port 13a. The size of the discharge port 13a is adapted to a single plate T, allowing only a single plate T to pass through. The plate T falls freely from the discharge port 13a onto the first conveyor belt 2a of the first conveying mechanism 2 by its own weight, and is separated one by one by the blocks 2b provided on the first conveyor belt 2a and conveyed downstream.

[0040] The working principle of the automatic CNC tenon and grooving machine in this embodiment is as follows:

[0041] 1. Feeding: The bamboo or wooden boards T to be processed are stacked into the feeding hopper 13. The boards T fall one by one from the discharge port 13a at the bottom of the feeding hopper 13 under their own weight onto the first conveyor belt 2a of the first conveying mechanism 2. The blocks 2b on the first conveyor belt 2a separate adjacent boards T and maintain a fixed distance for forward conveying.

[0042] 2. Tenon and Muzzle Machining: When the plate T moves with the first conveyor belt 2a between the tenon and muzzle machining unit 3 and the muzzle machining unit 4, the first rolling pressure roller 8 presses against the upper surface of the plate T to prevent shaking during machining. Simultaneously, the first motor 3b drives the tenon machining tool 3a to rotate, and the second motor 4b drives the muzzle machining tool 4a to rotate, synchronously cutting the left and right sides of the plate T to form the tenon and muzzle. (See details...) Figure 3 As shown.

[0043] 3. Plate T transfer: After the male and female tenons are processed, the plate T moves to the discharge end with the first conveyor belt 2a. Under the action of gravity, it slides down the guide plate 7. The limiting block 7a constrains the conveying path of the plate T to avoid deviation. At this time, the limiting plate 11 is in the rising state under the control of the second driving member 11a, allowing the plate T to pass and slide into the second conveyor belt 5a of the second conveying mechanism 5.

[0044] 4. Groove Machining: Plate T moves with the second conveyor belt 5a. Because the second conveyor belt 5a and the guide plate 7 have the same inclination angle, the transfer process is smooth and without jamming. The retaining edge 5b prevents plate T from falling laterally. Plate T first passes the auxiliary conveyor wheel 10. The first driving component 10a drives the auxiliary conveyor wheel 10 to rotate, which, together with the second conveyor belt 5a, stably delivers plate T to the groove machining position. Subsequently, the second rolling pressure roller 9 presses plate T, and the third motor 6b drives the groove machining tool 6a to rotate, cutting a straight groove on the upper surface of plate T. See the details below. Figure 4 As shown.

[0045] 5. Auxiliary Functions: During processing, the dust cover 12 draws the dust generated during cutting to the collection device through the negative pressure air pipe 12a, reducing dust pollution. If the plates T on the second conveyor belt 5a are about to accumulate, the limit plate 11 descends under the control of the second drive component 11a to block subsequent plates T from entering. It rises again to release the plates T after processing, ensuring orderly processing. See details for further information. Figure 2 As shown.

[0046] Through the above structure and process, the automatic CNC tenon and grooving integrated machine in this embodiment realizes continuous and integrated processing of tenons and straight grooves, effectively improving the processing efficiency and precision of bamboo and wood products. Please refer to the finished T-shaped board for the processing results. Figure 5 As shown, T1 is the male tenon, T2 is the female tenon, and T3 is a straight groove.
